Fixed in main:

 error: referencing initializer 'init(_:content:)' on 'ForEach' requires that 'TagType' conform to 'Identifiable'
            ForEach(TagType.allCases) { tag in
            ^
SwiftUI.ForEach:2:11: note: where 'Data.Element' = 'TagType'
extension ForEach where ID == Data.Element.ID, Content : View, Data.Element : Identifiable {
          ^

iandundas (JIRA User) Please use the latest snapshot of main branch from swift.org to verify and close.
